well within limits...there is a point where the sleeve just won't hold up, but its probably somewhere well over the 300 mark, probably high 300's somewhere, possibly 400, but that may be a stretch.

 

I know one guy who is pushing 421whp @ 25psi on stock sleves. ran an 11.8 or something.

here was his setup. his tuner is my idol. courtney green from SLC. best tuner in the west coast I think. this engine has lasted quite a while, most in part to his tuning.
(p.s. the setup is copy/pasted, I have better spelling skills than that lol)

98 ex coupe
srp pistons 75.5MM
crower rods
stock sleaves,head,cam,throttle body,intake manifold,tranny and axles
rc 550 injectors
hondata 3B
jun flywheel
act exteam plate
mccloud 4 puck sprung disk
drag manifold
persision SC61
PWR FMIC.

 

does courtney drive the red hatch w/ built gsr turbo? also, those 550cc's can support 21psi?

 

wow, all that on a stock sleeve with a .020 overbore. Impressive.

 

I thought i saw someone put down 403whp on stock sleeves on a built d awhile back on HT....

 

yea I was curious about the injectors myself, but I saw it first-hand. Courtney is the guy with the red hatch you were thinking about, except one of his friends wrecked that 10 sec car, and now he drives a gunmetal eg hatch thats running 10.2 with the same engine. what's bad *** is it's kinda junkyardish, like he made the mani himself, runs stock axles, stock cx radiator, its not that nice of a car, and it's his daily driver. What's even worse is his 60' on the 10.2 was 1.9. If he could pull a 1.6 like some of those 10 sec hondas, he'd be easily into the nines. he is just one smart ------- tuner thats all.

Here is a pic I took one night while tuning my friends car, sorry bought the quality and size.

 

i knew it! i saw that hatch ran 10 something at the last RMR Midnight Drags and i thought he painted his car! cool hatch

 

so where are you from man?

 

logan utah!

 

damnit sem your damn sig slows the ---- out of my pc and its only your that does it....
